Context: I run a German cannabis-growing knowledge site and built an internal diagnosis tool backed by a structured database of ~80 growing problems (deficiencies, pests, diseases, environmental stress). Pulled out a reduced, public excerpt as an open dataset — thought it might be useful beyond my own project, e.g. for anyone building a plant-diagnosis tool, chatbot, or just wanting structured agricultural data that isn't paywalled.

It's intentionally reduced — remedies and differential-diagnosis logic stay in the full (non-public) system, this is the descriptive/symptom layer only. CC BY 4.0, so reuse is fine with attribution.

Feedback on structure/fields welcome — this is v1.
